  • Type : UART type

Software Support

We provide a library for the LTE Cat.1 2 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for LTE Cat.1 2 Click driver.

Standard key functions :

Example key functions :

Example Description

Application example shows device capability of connecting to the network and

sending SMS, TCP/UDP messages or calling the selected number using standard "AT" commands.

The demo application is composed of two sections :

Application Init

Sets the device configuration for sending SMS, TCP/UDP messages or calling the selected number.

void application_init ( void )
{
log_cfg_t log_cfg;
ltecat12_cfg_t ltecat12_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ltecat12_cfg_setup( &ltecat12_cfg );
LTECAT12_MAP_MIKROBUS( ltecat12_cfg, MIKROBUS_1 );
if ( UART_ERROR == ltecat12_init( &ltecat12, &ltecat12_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
ltecat12_process( );
ltecat12_clear_app_buf( );
// Restart device
#define RESTART_DEVICE "1,1"
error_flag = ltecat12_rsp_check( LTECAT12_RSP_SYSSTART );
ltecat12_error_check( error_flag );
// Check communication
error_flag = ltecat12_rsp_check( LTECAT12_RSP_OK );
ltecat12_error_check( error_flag );
log_info( &logger, " Application Task " );
}

Application Task

Depending on the selected demo example, it sends an SMS message

(in PDU or TXT mode) or a TCP/UDP message or calls the selected number.

void application_task ( void )
{
switch ( example_state )
{
{
if ( LTECAT12_OK == ltecat12_cfg_for_network( ) )
{
}
break;
}
{
if ( LTECAT12_OK == ltecat12_check_connection( ) )
{
}
break;
}
{
if ( LTECAT12_OK == ltecat12_cfg_for_example( ) )
{
example_state = LTECAT12_EXAMPLE;
}
break;
}
{
ltecat12_example( );
break;
}
default:
{
log_error( &logger, " Example state." );
break;
}
}
}

Note

In order for the examples to work, user needs to set the APN and SMSC (SMS PDU mode only)

of entered SIM card as well as the phone number (SMS mode only) to which he wants to send an SMS. Enter valid values for the following macros: SIM_APN, SIM_SMSC and PHONE_NUMBER_TO_MESSAGE.

Example:

  • SIM_APN "internet"
  • SIM_SMSC "+381610401"
  • PHONE_NUMBER_TO_MESSAGE "+381659999999"

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LTECat12

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
